Wet Grinding VS Dry Ball Mill Grinding
Batch Ball Mill Grinding. Capacities and efficiencies in wet and dry ball milling at different speeds and ore charges have been discussed in the foregoing pages. The results are summarized in table 16, which shows that in both capacity and efficiency grinding was at its best with small ore charges and high speed.
Effect of Grinding Media on Milling
Effect of Ball Diameter, or Rod Diameter Variation. The first relationship to be considered is the effect of the variation of the ball diameter, or rod diameter, upon the size distribution obtained. In Fig. 6.1 are shown typical size frequency curves obtained by ball milling; these curves being deduced from the data of Coghill and Devaney.
